v UNITED STATES .PATENT OFFICE BOYS. SANFORD, OF SOUTH BEND, INDIANA, ASSIGNOR TO IBENDIX BRAKE COMPANY, OF SOUTH BEND, INDIANA, A CORPOR TION OF ILLINOIS LEVER CONNECTION Application filed August 15 1927. Serial No. 13,177.

This invention relates to operating mech- I anism, as for example a part of the chassis hookup of a set of-four-wheel automobile brakes, and is illustrated as embodied in a novel arm adjustably mounted .on an operating shaft. Preferably the arm is formed with spaced sides having openings embracing the shaft, and which openings or the shaft or both may be serrated if desired, and means such as a clamp bolt is provided for pinching the sides toward each other when the arm is in its desired adjusted angular position, thus causing the openings to bind on the shaft to clamp the arm firmly in lace.

The above and other objects an features of the invention, including various novel and desirable details of construction, will be apparent from the following description. of

one illustrative embodiment, shown in the accompanying drawings, in which: j

Figure l is a section through the shaf just inside the arm and showing the arm in side elevation; and

Figure 2 is a rear elevation of the parts shown in Figure 1 and looking from the left in Figure 1.

The novel operating mechanism illustrated in the drawings includes an angularly movable shaft 10, which may be one of the shafts of the chassis hookup in a set of fourwheel automobile brakes, and on which is mounted a novel lever 12 arranged to be adjusted angularly on the shaft when desired. Preferably the arm 12 is generally channel-shaped, to providesides 14 formed with openings for the shaft 10, the openings or the shaft or both being serrated if desired to provide for positive interlocking when the arm is in any desired angular position. The openings in the sides 14'are just enough larger than the shaft 10 to permit the arm to be turned on the shaft. When turned to a desired. angular position, the arm is locked in place by pinching the "sides 14 toward each other 'by means such as a clamp bolt 16 passing through suitable projections such as ears 14' in the sides 14 in parallel relation to the shaft 10. This causes the sides 14 to bind tightly on the shaft, thus locking the arm 12 firmly in its adjusted position,

While one illustrative embodiment has ends of the arm through which the boltextends, said ears extending at right angles and laterally of said shaft in close proximity thereto.

2. In combination, a shaft, an arm having spaced sides formed with openings embracing'the shaft, and means for pinching said sides toward each other to cause the walls of said openings to bind on the shaft,

to clamp the arm on the shaft.

3. In combination, a shaft, an arm having spaced sides formed with openings embracing the shaft, and a clamp bolt for pinching said sides toward eachother to cause the walls of said openings-to bind on the shaft, to clamp the arm on the shaft.

In testimony whereof, I have hereunto signed my name;

. ROY S. SANFORD.
